[PATCH] docbook-utils-native: Fix re-execution of the unpack task

[Richard Purdie <richard.purdie@linuxfoundation.org>]

If the do_unpack task is re-executed, the sed_done stamp was not removed, the
sed commands wouldn't re-run and the build would fail in do_compile. This
patch ensures the stamp is in ${S} and that we clean that directory
when unpack runs so it is a build from sctatch at that point.

[YOCTO #2194]
